At least since August 2015, we've been following the guideline [1][2] for
2LGTMs and to squash changes when they are accepted. AFAIK RMs for 4.6+ have
been asking PR authors to squash their changes before merging the PR once their
PR is accepted, the consensus has been followed and enforced.
I've only requested the PR authors to follow what has been followed in the
community/PRs for a very long time, however I encourage any disagreements to be
debated on dev ML than be discussed and burried in a pull request as this
affects everyone. /cc @karuturi
As an individual contributor, I prefer squashing changes for a single
feature/FR into one or fewer commits. Sometimes, it may make sense to squash
changes to more than one commit though 90 seems like an outrageous number. If
multiple authors have worked on the PR, authors can consider squashing changes
to lowest possible grouped/squashed changes. Lastly, we've also seen several
feature PRs with several kloc+ changes that were accepted as a single squashed
commit that may be searched through Github PR search page.
